The next time you find yourself staring down a “request for permission” screen on your Facebook account you might want to think twice, then three or four more times before you choose”Allow” for your new application.

Facebook has announced that they are now allowing developers to grab extra personal data from users, including their address and mobile phone number.

In the past Facebook privacy settings has barred sending phone numbers and address information to developers, relying instead on the users name, gender, a list of their friends and other already available public information.

Facebook is rushing to ease user fears, stating that developers can only access information when users explicitly give them permission and that all data use is governed by Facebook’s Platform Policies, which in most cases hold absolutely no guarantees to users and instead rely on app developers to properly use data they have received.

On the one hand, users have to choose whether or not to allow for their data to be mined, on the other hand, many users have “programmed” themselves to simply click “Allow” when signing up for new third party programs.
